Hi Everyone, I need some help with my bluetooth retrofit progress into an 07' 328xi.

So I've nstalled all necessary parts, connected the battery and BOOM, I was hit with an airbag error. The FZD (Roof Module)'s moonroof and interior lights would not work, but the SOS button did and I was able to successfully make a call and speak with BMW Assist.

I brought the car to the dealer to get coded, but they've had the car since last Wednesday and can't seem to get the FZD coded or working at all. They had opened up a PUMA case, and it even went to the top level manager of PUMA cases. I've been charged 4 hours of labor for the install (Alarm Install, Sirius, Alarm and TCU Coding, MOST BUS wiring) and I want to know if I'm getting BS'd around and getting charged up the wazoo because the dealer doesn't know what they're doing.

Now my dealer is telling me that I need to purchase a specific FZD and TCU in a pair otherwise my car will not code correctly. The part # of the FZD I was using is 61316976340 and the TCU part # is 84109181276. The dealer has even tried their own TCU and the car will not code.

Did you ever get the problem resolved? I am very interested in knowing because it seems like I have the same exact problem.. I posted the two threads linked to below but nobody has been able to help.. I am so frustrated becuase nothing seems to help, hopefully you have found the issue?
